增强MR血管造影在儿童先天性心脏病诊断中的应用

Application of contract enhancement MR angiography in diagnosing children′ s congenital heart disease

目的 评价儿童先天性心脏病 (简称先心病 )患者MRI检查 ,特别是增强磁共振血管造影术 (CE MRA)的诊断价值与不足。方法 30 0例儿童先心病患者作CE MRA检查 ,其中 173例 2 2 8个心内结构异常和 10 5个心外大血管异常已经手术证实 ,并与MRI及CE MRA诊断结果作对照。结果在 2 2 8个手术证实的心内结构异常 (主要为间隔缺损与瓣膜病变 )中 ,196个诊断正确 (86 0 % ) ;在10 5个心外大血管异常中 ,10 1个诊断正确 (96 .2 % )。结论 对心外大血管畸形MRI及CE MRA有很高的诊断价值 ,CE

Objective To evaluate the clinical diagnostic value and limitation of MRI and contrast enhancement MRA (CE-MRA) in congenital heart disease of children. Methods Three hundred patients with congenital heart disease underwent CE-MRA. 173 were confirmed by operation. The results of MRA and CE-MRA were compared with operation data. Results 196 (86.0%) intracardiac malformation including septal defect and valve anomaly were diagnosed correctly by MRI within 228 abnormalities which were confirmed by operation. 101 (96.2%) extracardiac malformation including great vessels stenosis and anomalous connection were diagnosed correctly by MRI and MRA within 105 abnormalities which were confirmed by operation. Conclusion MRI and CE-MRA are very accurate diagnostic method for extracardiac malformation. CE-MRA is the best sequence for congenital heart disease.
